Thepresent inventionrelates to a bed or couch spring and particularly toa bed or couch spring provided with side strengthening members.

In bed springs heretofore used, attempts have been made to impart extra.rigidity to the side members to prevent excess sagging when someone saton the edge of the bed. However, none of these attempts have beenentirely successful. By constructing a bed spring which embodies thepresent invention the resulting structure will be one that has extrasupport applied to theside member-step thatgifvsomeone sits on the edgeof the bed it will not sag abnormally. The-added rigidity, however, inno way interferes with .the overall comfort ,in the normal utilization.of the bed spring.

Another object of the present invention is to provide a pair ,of sidemembers and supports therefor that will prevent thelside members frommovinginwardly and thereby contracting the total supporting surfaceavailable for the mattress. A bed spring embodying the present inventionpresents a supporting surface that extend the full width of thesupporting cross pieces for the bed spring at the head and foot of thebed.

It is another object of the present invention to provide a bed springthat will, in use, have a much greater chance of preventing a surfacethat will catch a sheet or mattress and cause it to tear, from cominginto contact with said sheet or mattress.

One feature of the present invention is the use of a plurality ofsuspension springs for supporting the side strengthenin members, and thefact that these suspension springs do not all lie in the same horizontalplane. Some of the supporting springs that are secured to the sidestrengthening member lie in the same horizontal plane as the sidestrengthening member and others lie in a plane at an angle with theplane side strengthening members. This greatly increases the tensionforce available to securely hold the side strengthening members inposition, and contributes toward the attainment of the objects of thepresent invention above listed.

These and other objects and advantages of the present invention will bemore readily understood from the following description and drawing ofone specific embodiment of the present'invention, in which drawing:

Fig. 2 is a side elevation thereof;

:The-;-bedsspring:has:theusual; rigid. frameieonsisting of transversesupporting :members :10; at the head anidifoot,and-the.longitudinaliitubular member-ll to which. theztransversezmemberIt is secured. v

'lIlhezsidezstreng'thenlng members 12 are secured to the -;transversesupporting members :16 by means of ,a plurality of .helical springs.These springs consist of two group he p ings 1-3. which-lie inthehorizontalplane, v andsthe springs l4 which-liein-a plane-at ananglewith the horizontal. The, rigid partof the side strengthening member .12is the angle'iron IS. The angle iron 15 isbent at its ends ,to form theshort segments l6 parallel tothe transverse supporting members I0.Rivettedto the ends ofthe shortsegments l6, and connecting both of them,is metal strip IT. The strip I1 is much Wider in the horizontal planethan it is thick in the vertical plane. Thus the strip [1 will beresilient in the vertical plane but not in the horizontal plane.

Located within the side'strengthening member I2 is a resilientsupporting structure as is found in many bed springs comprising thecable 3 held under tension by helical springs I9, hooked to the shortsegments l6, and secured to the angle iron l5 by clips 20, and to themetal strip I1 by the clips 2|; of course a conventional link structuremay be used.

As can best be seen in Figs. 3 and 4, the helical supporting springs l3and M for the side strengthening member l2 are hooked into opening 22 inthe transverse supporting bar It and into openings 23 and 24 in thesegment it of the angle iron l5. The openings 23 in the horizontalportion of the angle iron l5 secure the horizontal springs l3 and theopening 24 in the vertical portion of the angle iron 15 support thesprings l4.

Since there are a plurality of springs 13 and H3 securing the rigidangle irons l 5 to the transverse supporting bars It, the sides of thebed spring will be greatly strengthened. Moreover, the fact that thesprings I4 do not lie in the horizontal plane adds greatly to the amountof force it will take to force the sides of the bed spring downwardlyince they will react to a vertical force primarily by expanding alongtheir longitudinal axis rather than bending, as will springs in thehorizontal plane.

The structure as shown in Figs. 3 and 4 is repeated at all four cornersof the bed spring. The central portion of the bed spring may comprisethe conventional cable structure 25, as shown, or a conventional linkstructure secured to the supporting bars by helical springs. As bestseen in Figs. 3 and 5, the central cable structure 25 is linked to thecable I8 by the clips 2|.

Since the corner 26 is rounded due to the fact that the angle iron 15 isbent at right angles to form the segment 16, no sharp corner ispresented that will tear sheets, or a mattress. The conventional angleiron at this point has a very sharp corner that is prone to tear sheetsand mattresses.

I claim:

1. A bed spring comprising a rigid frame, two side strengthening parts,each of said side strengthening parts comprising a rigid member having along portion extending substantially from one end of the spring frame tothe other and terminating at each end in a short horizontal portion atright angles to said long portion, a plurality of groups of springssecuring each end of said side strengthening parts to the rigid frame,and a bed sprin cable structure interposed between said two sidestrengthening parts and secured to the rigid frame, said bed springincluding a rigid metal strip connecting the ends of the short portionsof each side part.

2. A bed spring comprisin a rigid frame, two side strengthening parts,each of said side strengthening parts comprising a rigid member having along portion extending substantially from one end of the spring frame tothe other and terminating at each end in a short horizontal portion atright angles to said long portion, a plurality of groups of springssecuring each end of said side strengthening parts to the rigid frame,and a bed spring cable structure interposed between said two sidestrengthening parts and secured to the rigid frame, said bed springincluding a strip connecting the ends of the short portions of each sidepart, and a second bed spring '4 cable structure secured to the sidestrengthening parts between the long portion of the rigid member and thestrip.

3. A bed spring comprising a rigid frame, two side strengthening parts,each of said side strengthening parts comprising a rigid member having along portion extending substantially from one end of the spring frame tothe other and terminating at each end in a short horizontal portion atright angles to said long portion, a plurality of groups of springssecuring each end of said side strengthening parts to the rigid frame,and a bed spring cable structure interposed between said two sidestrengthenin parts and secured to the rigid frame, said bed springincluding a strip connecting the ends of the short portions of each sidepart, and a, second bed spring cable structure secured to the sidestrengthening parts between the long portion of the rigid member and thestrip, said second bed spring cable structure being linked with thefirst mentioned bed spring cable structure.
